Opened in 2019, the Sierra Vista Family Dental Center is CCHCI’s largest dental program, offering comprehensive services right in the heart of Sierra Vista. Here, preventive, emergency, and restorative dental care is available for the whole family—from infants to seniors.
Our services include infant oral health exams and risk assessments for conditions like tooth decay, preventive cleanings, fluoride varnish treatments, nutrition counseling, and habit control (like pacifier or thumb-sucking support). We also handle cavity repairs, gum disease treatment, dental injuries, oral surgery, prosthetic dentistry, and even cosmetic procedures—all delivered with a child-centered approach.
Understanding that children aren’t “small adults,” our dental providers are trained to put young patients at ease. Whether it’s calming exam rooms, gentle explanations, or playful distractions, we make dental care a positive experience for kids.
Our clinic operates Monday through Thursday from 7:30 AM to 6:00 PM (closed noon–1:00 PM for lunch), and Fridays from 8:00 AM to 5:00 PM. We’re also open on the first and third Saturdays of each month, from 9:00 AM to 3:00 PM—making scheduling care easier for working families.
Whether you’re scheduling a check-up for your child, seeking restoration or cosmetic dentistry for yourself, or managing a dental emergency—Sierra Vista Family Dental Center is here to help. Trust us for compassionate, comprehensive dental care tailored to you and your family.

Why I Believe in the Mission of CCHCI:
"The ability to provide healthcare should never be based on financial incentives. To be able to put a healthy, confident smile on our patients' faces is my personal measure of success."
I believe patients should be able to receive access to healthcare regardless of their ability to pay. I care about the well-being of others and believe they should not suffer with pain or illness when there is treatment available to resolve it.

I believe in having the ability to focus on the patients’ needs without the concerns or pressures of a for-profit system. Seeing the improved health, increased self-esteem, and gratitude from the patients, is a priceless reward.
I am a married, third generation Arizona native with two adult children. I started a private practice from scratch in Ventura, California. After thirty years, I sold the practice and tried to retire as a Gentleman Rancher; that was short-lived as the love of dentistry led me out of retirement and to CCHCI. When I am not repairing smiles, I enjoy horses and golf.

Committed to delivering high-quality, compassionate dental care, Dr. Han focuses on improving the oral health and overall well-being of patients of all ages throughout the Sierra Vista community.
Coming from an immigrant family, I have witnessed and experienced firsthand the barriers that can make accessing healthcare difficult. I believe in CCHCI’s mission of “healthcare for all” because everyone deserves compassionate, accessible care regardless of their background or circumstance.
I was born and raised in South Korea. My family immigrated to the U.S. when I was 16 years old. I joined the U.S. Army in 2014 as an active-duty Behavioral Health Specialist, serving for 4 years, followed by 1 year in the U.S. Army Reserve. Working at the hospital, I grew my passion for patient care. Following my military service, I returned to school and finished my undergraduate degree in Biology at Claremont McKenna College. Afterward, I attended the University of Maryland School of Dentistry and received a Doctor of Dental Surgery degree (DDS).
